From your last logfile (http://pastebin.com/RCKePPas):

[roslaunch][ERROR] 1969-12-31 17:01:13,760: OSError(8, Exec format error)
[roslaunch][ERROR] 1969-12-31 17:01:13,763: Unable to launch [rosout-1].

... seems to be the relevant error. I don't know anything about the BeagleBoard but since it's not x86 (correct?) I'm guessing you have some cross-compilation issues.

Almost certainly the case. Beagleboard is an ARM board. There has been some work started over here: http://dave.limoilux.org/trac/wiki/ROS/CrossCompile/arm but it's far from complete. You can probably also work off the gumROS guide: http://www.ros.org/wiki/gumros as a starter.

Do you have a log file? How is your hostname and IP configuration? Could you try to launch it with export ROS_MASTER_URI=http://localhost:11311? Perhaps the XML RPC couldn't reach itself because it has no DNS resolving for Evolve. Could you also try:
